Task failed for installing Selinux on App server 1 in Stratos Datacenter

I have completed the task by SSH on to tony@172.16.238.10 and installing the Selinux using the commands

yum install selinux-policy-targeted

yum install selinux-policy-devel policycoreutils

After that I checked sestatus and it was showing as disable on the stapp01 (stapp01.stratos.xfusioncorp.com). I came out of server by exiting from stapp01 terminal.
When I submitted the work, the task was unsucessfull.

You need to Change the SELINUX value to SELINUX=disabled in the file /etc/selinux/config.

Thanks for the response.Since I was getting the status as “disabled” on checking via cmd sestatus.So i did not changed the config file.

After reboot,perhaps the config file changes would matter.Thanks for pointing out.
